“Dynamic finders with hash attributes for creation”

Here’s a typical situation:

tag = Tag.find_by_name(name)
if tag.nil?
tag = Tag.create(:name => name, :creator => current_user)
end

You’d think the way to do that would be with the find_or_create_by_name dynamic finder, but that doesn’t work since there’s no way to search by name only, but create by name and creator. Well, that’s just not right. So here’s what we’ll do:

Tag.find_or_create_by_name(:name => name, :creator => current_user)

It’s not a big deal or something I use every day, but I like it anyway.
